This application is a continuation of and claims priority to U.S. patentapplication Ser. No. 15/967,140, filed Apr. 30, 2018, which is acontinuation of U.S. patent application Ser. No. 13/844,552 filed Mar.15, 2013, now U.S. Pat. No. 9,959,581, entitled “Property Management ona Smartphone,” the entire contents of which are hereby incorporatedherein by reference.

BACKGROUND Technical Field

The present disclosure relates to systems and methods used to track andmanage multiple properties and the various attributes andcharacteristics of each property and buildings on the property on asmartphone or mobile device.

Description of the Related Art

Property management systems that track conditions, features, and otherattributes of one or more properties have typically used paper-basedsystems that have involved manual updates when property data is changedor new properties to manage are added. In some instances, features andattributes of different properties have been stored as individualrecords in a database, for example a government database containingproperty records for parcel numbers, address, year built, square footageestimate, and the like.

Pitch determination systems that are used, for example, to determine apitch of a roof have traditionally involved a person visiting theproperty and measuring the roof using a tape measure and level.Recently, systems have been introduced by EagleView Technologies, Inc.that allow multiple aerial images to be used to render athree-dimensional model of the roof and to produce a roof report fromwhich the pitch of a roof may be determined.

BRIEF SUMMARY

In one embodiment, a property management system operates on a smartphonedevice and allows a user to identify one or more properties to bemanaged, to order a roof report for the one or more properties and tohave the result of that roof report returned to and stored on thesmartphone device. The property management system also allows thesmartphone user to edit or add data associated with the property,including the roof report for the property, by adding photos, editingphotos, annotating photos, and updating and adding text information tothe property data stored on the smartphone.

Systems and methods for determining pitch are also disclosed that allowa smartphone to be used to determine the pitch of a facet of an object.In one embodiment, the smartphone uses an image representing a facet ofan object for which a pitch is to be determined and receives anindication from a user of the start and end point of a line on thefacet. The system uses metadata information contained in the image andthe indication of the facet to determine the pitch of the facet. Inanother embodiment, the system allows a user to take a picture of thefacet to be measured with a smartphone camera. The system uses featuresof the phone, such as the accelerometer, to determine the orientation ofthe camera when the picture was taken. This information, along with theuser's identification of the facet to be measured, is used to determinethe pitch of the facet. In other embodiments, visual recognition is usedto identify a facet within an image and to calculate the pitch of thefacet.

DETAILED DESCRIPTION

FIG. 1 shows one embodiment of a block diagram of a computer hardwaresystem to obtain and described herein provide enhanced computer- andnetwork-based methods, techniques, and systems for building structureestimation employing perspective imagery from independent sources.

FIG. 1 is therefore one example block diagram of a computing system 100for practicing embodiments of the statistical point pattern matchingmethod described herein, and for practicing embodiments of a buildingstructure estimation system based on the point pattern matching,according to one embodiment.

One or more general purpose or special purpose computing systems may beused to implement the computer- and network-based methods, techniques,and systems for point pattern matching computation described herein andfor practicing embodiments of a building structure estimation systembased on the point pattern matching. More specifically, the computingsystem 100 may comprise one or more distinct computing systems presentat distributed locations. In addition, each block shown may representone or more such blocks as appropriate to a specific embodiment or maybe combined with other blocks. Moreover, in one example embodiment, thevarious components of a Building structure estimation system 114 mayphysically reside on one or more machines, which use standardinter-process communication mechanisms (e.g., TCP/IP) to communicatewith each other. Further, the Building structure estimation system 114may be implemented in software, hardware, firmware, or in somecombination to achieve the capabilities described herein.

Examples of computing systems and methods to obtain a roof report areshown and described in detail in U.S. Pat. Nos. 8,078,436 and 8,170,840and these can be used as one component of the present embodiment, aswell as other roof report generation systems. For completeness, onepotential system for creating such a report will be described herein asfollows.

In the embodiment shown, the computing system 100 comprises a computermemory (“memory”) 102, a display 104, one or more Central ProcessingUnits (“CPU”) 106, Input/Output devices 108 (e.g., keyboard, mouse,joystick, track pad, CRT or LCD display, and the like), othercomputer-readable media 110, and network connections 112. A buildingstructure estimation system 114 is shown residing in the memory 102. Inother embodiments, some portion of the contents or some or all of thecomponents of the building structure estimation system 114 may be storedon and/or transmitted over the other computer-readable media 110. Thecomponents of the building structure estimation system 114 preferablyexecute on one or more CPUs 106 and generate roof estimate reports, asdescribed herein. Other code or programs 116 (e.g., a Web server, adatabase management system, and the like) and potentially other datarepositories, such as data repository 118, also reside in the memory102, and preferably execute on one or more CPUs 106. Not all of thecomponents in FIG. 1 are required for each implementation. For example,some embodiments embedded in other software do not provide means foruser input, for display, for a customer computing system, or othercomponents. Currently, some inputs to the building structure estimationsystem 114 are automatically generated, but other inputs may be enteredmanually to supplement data acquired through automated means. Furtherautomation of the building structure estimation system, includingautomation of roof materials overage estimation is a goal addressed bythe method described herein, along with other methods.

In a typical embodiment, the building structure estimation system 114includes an image acquisition engine 120; a roof modeling engine 122; apoint pattern matching computation engine 124, and a roof materialsoverage computation engine 125 within, or as part of, the roof modelingengine 122; a report generation engine 126, an interface engine 128, anda data repository 130. Other and/or different modules may beimplemented. In addition, the building structure estimation system 114interacts via a network 132 with an image source computing system 134,an operator computing system 136, and/or a customer computing system138. Communication system 132 may utilize one or more protocols tocommunicate via one or more physical networks, including local areanetworks, wireless networks, dedicated lines, intranets, the Internet,and the like.

The image acquisition engine 120 performs at least some of the functionsdescribed herein, with respect to the processes described herein. Inparticular, the image acquisition engine 120 interacts with the imagesource computing system 134 to obtain one or more images of a building,and stores those images in the building structure estimation system datarepository 130 for processing by other components of the buildingstructure estimation system 114.

The roof modeling engine 122 performs at least some of the functionsdescribed with reference to FIGS. 2-13 below. In particular, the roofmodeling engine 122 generates a model based on one or more images of abuilding that are obtained from the building structure estimation systemdata repository 130 or directly from the image source computing system134. As noted, model generation may be performed semi-automatically,based on at least some inputs received from the operator computingsystem 136.

In addition, at least some aspects of the model generation may beperformed automatically. In particular, to generate a 3D model, the roofmodeling engine 122 may use output from the point pattern matchingcomputation engine 124 which employs variational analysis to compute apoint-to-point probability spread function. The point-to-pointprobability spread function can be used to estimate which individualpoints on one image of the building most likely match correspondingpoints on another image of the building (i.e., the point patternmatching computation engine endeavors to “optimize” point matchingassociations). This estimation may be based on adaptive predominancevoting probabilities generated from shape pattern matches. The shapepattern matches can be created by comparing combinations of points on anorthogonal view of the building with specific other points on an obliqueview of the building, and as further described herein.

Property Management

FIGS. 2A-2AD describe systems and methods for using a smartphone tomanage multiple properties, and to access the attributes andcharacteristics of buildings on the properties. The term “smartphone” asused herein is intended in its broadest sense to include any Internetcapable small mobile device and as such includes within its meaning atablet, mini-computer or other mobile device that has a wirelessconnection to the Internet and an internal microprocessor.

In one or more embodiments, property management systems, includingsoftware modules may be used to track physical features of property,such as location of the property, valuation of the property, number ofbuildings on the property, and information about the buildings on theproperty. This information may include photographs of different areas ofindividual buildings such as roofs, walls, interiors, surrounding areasoutside the building structure such as groundcover, shrubs that may begrowing against the structure, and other building conditions that canvisually documented and assessed. Property management systems may alsobe used to store building information such as two-dimensional orthree-dimensional models of the building including the roof structure.Other information may be kept in a property management system includingownership of the property, taxes paid on the property, reports ofrepairs or insurance claims against structures of the property, and thelike.

The information stored in a property management system on a smartphonemay be implemented by entering all data directly into the smartphone,however the preferred embodiment is for property management informationto be shared between the smartphone at one or more property managementdatabases on a server. In this way, property management informationupdated at the server can be sent to the smartphone device, andinformation gathered by the property management system on the smartphonedevice can be used to update information for the property on the server.One embodiment of sharing would be to synchronize the database on thesmartphone via a web service that also queries the server database.

In one or more implementations, the system on the smartphone is able toretrieve information about properties that was acquired through productsthat were ordered about those properties. For example, roof reports,walls reports, solar reports, and other similar reports may be orderedfor a property from EagleView Technologies, Inc. These reports providedetailed analysis and description of characteristics of the propertythat include for example the number of facets on a roof, the pitch ofeach facet, the square footage of the roof, a three-dimensional model ofthe building, walls information for the building, total living areawithin the structure, and the like.

For example, a user at a property site, such as an insurance adjustor ora contractor, may use the property management system on the contractor'ssmartphone to determine if such a report exists for the property. If so,the user can look through the list of properties on the smartphone,locate the property, and view the property information. Optionally, theuser may query the server to see if updated information on the propertymay be available. If such a report does not exist for a property, thenthe user can order one from the property management system on thesmartphone. In some cases, the results of a report request may bereturned within several minutes. For example, if a contractor isavailable at a customer site and a report request is returned within theperiod of time that the contractor is at the property, the contractorwill be able to provide the customer with an accurate repair orconstruction bid estimate before the contractor leaves the property.This has the advantage of providing the property owner with a quick,accurate bid, and the advantage of not requiring separate trips onbehalf of the contractor to the property.

In some embodiments, in addition to reports other items may be requestedfor download, including data, diagrams, GIS data, and geometric modelsof buildings relevant to the property of interest and immediatesurrounding areas.

In one embodiment, if a three-dimensional model or diagram derived froma model already existed on the server because of a previous request fora model of a property or the property model was pre-computed for aparticular geographic area, a model of the property, including anyregeneration of diagrams or documents related to the model, would beimmediately downloaded to the smart phone. In the case that thethree-dimensional model was not on the smart phone or on the server, themodel, and any diagrams or documents derived from the model, would begenerated on demand from the imagery and associated image metadata forthe property, or from intermediate precursor data for the property suchas point clouds derived from the images and metadata.

Here, the property manager system onthe smartphone that has received detailed data on the structure of theroof, for example through a completed roof report order, and canconstruct a two-dimensional or three-dimensional diagram of the house.This diagram would then be shown on screen 227 for the user to assignpitches to individual facets of the building. In one or moreembodiments, this model of the house can be scrolled, or zoomed in orzoomed out to view the full structure, and to read or apply properpitches.

FIG. 2AB describes screen 228 which allows the user to change settingswithin the property manager system on the smartphone by selecting thesettings button on the lower right portion of the screen. Here, the usercan adjust account information, such as whether to use the currentlocation of the smartphone device as a location for the account, orwhether to automatically fetch order information corresponding to theaccount location, or whether to wait for the smartphone user to ask fororder information to be downloaded. In addition, the user can choosewhether to show claim ID within reports, and also specify additionalemail addresses to which reports should be sent.

FIG. 2AC shows screen 229 which is displayed by selecting the rightarrow next to “Fetch Order Info” on screen 228. Here, the user is ableto select how data that is updated on the server may be sent to thesmartphone. This data may include but is not limited to order status,order information, a final property report, or any otherproperty-related data, which may include three-dimensional models,diagrams, or data. A user may turn the push feature on if the user has alow-cost/high-bandwidth data connection such as a Wi-Fi connection. Ifthe user has a slower or more expensive data connection, the user mayturn the push feature off, and instead specify at what intervals datafrom the server should be fetched. In one embodiment described in screen229, the user is given the option to fetch data every 15 minutes, every30 minutes, hourly, or to not have data automatically fetched at all butrather wait for the user to manually ask for the data.

In other embodiments, different methods may be used to determine whatdata is sent from the server to the user's smartphone, and at what timeit is sent. For example, suppose a roof report for a property existsthat contains roof measurements, a three-dimensional model of the housestructure, pitch data for facets of the roof, total living area,property condition assessments, and several pictures of the house andsurrounding area. If this roof report on the server that was downloadedto the users smartphone device has been subsequently changed, forexample additional images of the property have been added to the reportat the server, it is not necessary to resend the entire roof report, butonly send the data that has changed. In one embodiment, this isaccomplished by looking at the timestamps of the relative files, andonly sending data from the server that has a timestamp newer that thetimestamp on the corresponding data on the smartphone device.

FIG. 2AD shows screen 230 which allows the user to designate data fieldsto display. Here, the user has the choice of Cat ID, claim number, batchID, or status.

Three Dimensional Models

FIGS. 4A-4E are examples of property estimation and inspection methodsand systems that run on smartphone or tablet devices that allow users tobuild, update, and use three-dimensional models of one or more buildingson a property. In some cases these three-dimensional models appear aswireframes, and may be used in conjunction with photos, report resultsdata, customer or user annotations, and data from any other source thatmay be related to the associated property.

There are a number of advantages for working with three-dimensionalmodels of buildings associated with the property. A user, which may be acontractor, can easily interact with the customer at the buildinglocation to help the customer choose a feature for the structure, suchas a certain type of siding for the walls of the structure, or type ofshingles for the roof. The contractor can select and apply examples ofhow the materials would appear on the structure, and then allow thecustomer to rotate the structure to see how the material would appear atdifferent angles. The advantage for both the customer and the contractoris a quicker decision from the customer that matches the customer'stastes. In another example, an inspector or estimator will be able totake a tablet, walk around a property, and annotate features of abuilding to make notes that may affect repair or insurance estimates.For example, an inspector may note bricks extending halfway up a wall.In another example, on-site inspectors may be able to fill in additionalinformation to be included in the three-dimensional model that could notbe identified during the original analysis of the property using aerialimages. For example, a tree may block a deck or a window from view onthe side of a house that could not be seen without an on-site propertyinspection. In another example, an on-site inspector or estimator canmake annotations on the three-dimensional model, such as describingconditions of a particular area of a roof. A contractor may use this toshow area of damage to a customer, or to describe to the customer how aproposed chimney, a proposed skylight, or a proposed room addition mayappear in final form.

FIG. 4A shows screen 255 which displays a three-dimensional wireframerendering of a complex roof of a home. The three-dimensional model fromwhich this wireframe is rendered may have come from a roof report fromEagleView Technologies, Inc. that was ordered by a user using theproperty manager system on a smartphone device. The model informationmay have come from other sources or multiple sources, including updatesto three-dimensional model made by the tablet user when inspecting theproperty location. In this embodiment, the wireframe may be rotatedusing the pivot tool in the center of the diagram, zoomed in using themagnifying glass, or rotated in the third direction by using the uparrow with the side cross arrow through it. In addition, because this ispart of the property management system, a customer can place a new orderfor a product by clicking the new order button, can look at the myproperties information associated with the user, review orders, orchange settings as described above.

FIG. 4B shows screen 256 which differs from screen 255 in that a higherresolution for the wireframe image is used.

FIG. 5J shows screen 269 which is displayed when the effects button isselected. This allows the brightness in the contrast of the image to beadjusted to make the image easier to view if it was photographed inharsh light, such as in the early morning.

FIG. 5K shows screen 270 which is displayed when the user selects thefinger draw to this tool allows the user to highlight areas of interestby drawing a line around the area using the user's finger.

FIG. 5L shows screen 271 which is displayed when the user selects thenotes button. When selected, a keyboard is displayed that allows theuser to enter in extended amounts of text describing features or damageto the area being viewed. This text is not displayed on the image, butis rather associated with the image and available for later viewing.

FIG. 6 shows screen 272 which is displayed when the user selects theinspection tool, which in one embodiment shows a top-down image of thebuilding and allows a user to make annotations regarding the featuresand conditions of different areas of the structure. In one or moreembodiments, this data is collected from two-dimensional orthree-dimensional models that are captured in reports received by theproperty management system on the smartphone. In one example, the datafrom the reports received may be from an EagleView Technologies, Inc.roof report or walls report.

In some embodiments, annotations may include capturing or adding voicecommentary, either as a running commentary or as part of the datapackage that is tied or tagged to a marker or indicator that is placedon a model or associated with a model.

This inspection tool has many advantages. For example, for an insuranceclaim adjuster in the field, the adjuster can use this tool to updatethe model of the building to represent additions to the building thatdid not appear in the model. The adjuster can also use this model fordescribed damage done by hail, fire, or other disaster. Data needed torepair the defect, for example the type of material, the amount ofmaterial required, and the like may be represented on the diagram. Insome embodiments, the materials may be able to be ordered directly fromthe screen using pricing estimator models.

Insurance underwriters may also use this tool to either augment orverify the risk management analysis of the property when determininginsurability or premium amounts. For example, location of fire hydrantsmay be out of date or hard to see from aerial images. The existence andlocation of fire hydrants can be easily added using this tool.

In this embodiment, the user may identify different facets or areas ofthe structure, for example areas X, V, U and the like on the drawing toidentify the facet or to associate related facets with each other. Theuser may also place pushpin icons in different areas on the structure toidentify damage, or other features the user wishes to call out. Inaddition, the user can attach additional photos to this model, by usingthe camera within the tablet device or by associating an existing imagewith the model. In some embodiments, information can be retrieved bytouching different areas of the image. For example, the user can tap afacet on the model to get information on that facet such as squarefootage or pitch. Finally, the user is able to record conclusions basedon the on-site inspection work done at the represented building.

Pitch Determination

FIGS. 2Y-2AA, and FIGS. 7-13 describe systems and methods fordetermining the pitch of an object using a smartphone. For roofingcontractors and other related trades that use the slope of a roof, aconvenient, accurate assessment of the pitch angle of a section of roofis important. The ability to assess pitch using a mobile device like asmartphone or tablet computer while standing on the ground offers afaster, safer, and more convenient alternative to climbing onto the roofor scaling a ladder to directly assess a sloped section of a roof usingmechanical or electronic pitch gauges that require physical contact withthe measured surface.

One method to determine the pitch of an object uses the smartphonedevice in the capacity of a carpenter's level to directly measure pitch.FIG. 2Y shows one embodiment to determine the pitch of an object byplacing the smartphone device at the desired pitch angle, and pressingthe measure pitch button as shown. In this example, a level moduledetermines the angle of the smartphone device by using the accelerometerdata and orientation sensors within the smartphone to determine theangle of the smartphone in relation to level. In some embodiments, thesmartphone device may be held against an angled rafter to determine itsangle from level. FIG. 2Z shows one embodiment where the anglemeasurement is displayed on the smartphone device as a pitch value. FIG.2AA shows another embodiment where the output of a pitch value for afacet of a building may be directly imported as a pitch measurementassociated with a facet of the building that is represented in a twodimensional or three-dimensional model of the building.

Another embodiment of the method to determine the pitch of an object isbased on using the smartphone device as a video-based carpenter's levelas above. However, the actual smartphone device is not used as aphysical carpenter's level. Instead, a fixed projected horizontal lineis displayed on the smartphone camera display screen. The projectedhorizontal line stays fixed relative to the smartphone device, eventhough images on the camera display will move as the camera moves. Todetermine the pitch of one side of a gable of a house, the user standsaway from the house, points the smartphone camera at the house to seethe side of the gable to be measured within the camera's field of view.The user then rotates the smartphone until the projected horizontal lineappears to be parallel to the side of the gable to be measured. Thismethod uses the smartphone device's orientation sensors to determine theangle of the smartphone device and the resulting pitch of the gable. Theaccuracy of this method is improved as the user stands further away fromthe object to be measured.

Another method for determining the pitch of an object uses thesmartphone device to capture an image and other optional metadata suchas device orientation and information, and GPS location, and then drawmarkers on the image that overlay the surfaces where the pitch is to bedetermined. FIG. 7 shows a context diagram showing positions and anglesfor the disclosed method. A user with a smartphone 302 stands at adistance “d” 304 from a wall 314 to determine the angle of the rake 316of the roof of the structure. The ground-level is represented by 312.Line 306 represents the level line between the smartphone 303 to thevertical line 320 passing through point A 318 of the structure. Line 308represents the angle at which the smartphone 303 is being held inrelation to Horizontal Line 306

FIG. 10B shows an example of a photo of a house taken with a smartphonecamera, where the house has a gable feature 328. FIG. 12 shows anembodiment of a scissor marker that is a composite of two linear shapesformed by the line from point 330 to point 332, and the line from point330 to 334, that visually present two angled surfaces commonly found ongables and gabled dormers 328. When applying this method of determiningpitch, either a live image as seen on the smartphone camera display maybe used, or a captured image may be used.

FIG. 11 shows an example of a scissor marker within frame 328. 330represents the top of the scissor marker which is typically placed atthe vertex of the angle to be measured, for example the top peak of thegable structure. Moving point 330 will translate the entire markereither up or down on the image while leaving the angle of the scissormarker constant. To open or close the scissor marker, the user moveseither point 332 or point 334 in the direction of the arrows shown,which changes the opening angle of the scissor marker.

FIG. 12 shows three different examples 336, 338, and 340 that show howthe smartphone's orientation sensor can be used to maintain a propervertical orientation of the scissor marker in a live image. This way,the user does not need to worry about the orientation of the smartphonein their hand, whether it is in portrait 336, landscape 340 or a skewedorientation mode 338 in between. When dealing with a live image on thecamera, the camera can be moved until marker 330 is visually over theapex of the gable 328 to be measured. In that embodiment, the scissormarker may be fixed to a position on the screen such that the user canmanipulate the opening angle but cannot translate the marker's position.The user to manipulates the orientation of the smartphone, therebymanipulating the displayed image under the marker. Once the appropriatesection of the image is under the fixed position of the scissor marker,the opening angle of the marker can be modified to match the angles ofthe underlying roof image.

For a captured image, FIG. 8 shows an embodiment where the orientationmetadata captured with the image provides context by which the propervertical orientation can be achieved. The scissor marker may betranslated around the screen, by selecting 330 and moving it until it isvisually over the apex of the gable 318. In one embodiment, thismovement can be accomplished by the user touching marker 330 with afinger and dragging it to the proper location over the image. Likewise,the opening angle between the two linear shapes can be similarlyadjusted by moving 332 and 334, either symmetrically or independently,to cause their corresponding lines that connect with 330 to overlay theedge of the gable image to be measured.

A scissor marker may exist in a number of embodiments. In oneembodiment, a simple version is a half-scissor, for example consistingof a vertical reference and one adjustable arm. In another embodiment amore complex version may be a scissor that includes a third axespointing orthogonal to the plane of the scissor. In this example, such adevice could be used to orient and/or rotate the scissor cursor aboutthe z-axis to compensate for an angle between the viewer and the gabledface. In another embodiment, the scissor curser allows the user to slidethe apex of the cursor along that third axes, for example to tilt theplane of the scissor to access the pitch of a hipped face.

In the above embodiments describing pitch determination, additionalaccuracy can be achieved by making corrections of perceived pitch due tothe position of the smartphone's angle of observation. As the userapproaches the building of interest, the horizontal distance from theuser's mobile phone 303 to the gable as distance “d” 304 becomes smallerand the projection of the gable within the image will appear to “flattenout,” and reduce the perceived pitch angle of the gable. This effect isillustrated in FIGS. 9A and 9B. By determining the angle “alpha,” foundin FIG. 7 between 306 and 310, the perceived pitch of the aligned pitchdetermination marker can be corrected to yield the correct pitch value.To determine angle “alpha,” the smartphone's orientation sensors areused to capture the inclination of the smartphone device “phi”, theangle of the “normal” vector 308 coming out of the camera with respectto the ground 306, either at the time of image capture by the smartphoneor in real time when viewing a live image using the smartphone camera.Using the approximate knowledge of the angular field of view of thesmartphone camera, the angle “beta”, the angle between 308 and 310 iscalculated using the pixel displacement of the location of the apex ofthe pitch determination marker 330 (in FIG. 8 ) that overlays Point A318 (in FIG. 7 ) from the pixel located at the center of the image atPoint B. The sum of the angle “beta” and the angle “phi” yields thedesired value for the angle “alpha.”

FIG. 13 describes another embodiment of the method for determiningpitch, where the apex 318 of a gabled roof section is aligned with anactive region 346. This active region may be identified as a dashedcircle 346 that appears on the camera display of smartphone 303. In oneor more embodiments this active region 346 may be moved by selecting anddragging it on a still frame of an image. The active region 346 may alsobe in a fixed position within a live image such that the user must movethe smartphone camera to translate the desired roof apex in the liveimage under the active region. Once the active region is in position,computer vision algorithms which in one or more embodiments involve edgealgorithms or boundary detection algorithms are used to assess theopening angle of the gable 328 and report its respective pitch value. Inone or more embodiments, a pitch determination marker value isdisplayed, along with a highlight on the image to show the identifiededges used to determine the pitch.
